Update: Get Free Tips - Monitoring hard drive reliability

My hard drive makes weird noise and data access from it is extremely slow. Is it about to fail? Is there a way to predict hard drive failures?

While it is not possible to accurately predict a hard drive failure, advances in technology have made it possible to monitor certain aspects of hard drives and a deterioration of some of the values indicates a decline in reliability and possibly a near-time hard drive failure. All modern hard drives have an in-built self-monitoring system known as S.M.A.R.T or Self-Monitoring, Analysis and Reporting Technology. While electronic failures cannot be determined in advance, mechanical failures in a hard drive (constituting at least 60 percent of failure) give fair failure
indications. S.M.A.R.T provides certain attributes to determine hard drive failures —you can monitor your hard drive’s SMART attributes using free software like HDTune that can be freely downloaded from http://www.hdtune.com. If HDTune shows any of the attributes in yellow, you know there is a problem.
